Thanks for the response

Hotplug is detecting the modem....(cutcutpaste...)

Bus 001 Device 006: ID 04c1:3021 U.S. Robotics (3Com) 56k Voice FaxModem Pro

And the kernel is assigning it to abstract (virtual) port /dev/ACM0....the modem apparently is seeing activity on the port, because when I plug in the USB cable, the data and CTS/RTS LEDs flash for a second. But there's no response to
an AT command when sent from Minicom. I'm about ready to break out the 'scope or a logic probe to see if any data is actually being sent to the modem.

What should I try next?
